Not sure if it's overheating or a bad video/graphics card. They go away when I restart the computer but keep coming back.

Overheating does not normally cause red dots on the screen. The pixels are most likely failing. Try to update the video card drivers and see if it helps. if not , then take the laptop to a authorised service vendor, the display may need replacing.

Hello. The red dots or pixels are due to your video card being overused and/or heating. Try updating to the latest drivers for your video card. You can find the latest drivers for your computer here: http://goo.gl/DJrDK

Hi

It seems that you need to use the latest driver for the graphic card.

You can do that through visiting the manufacture's website, choose your laptop model, OS, look for video (vga) driver, and download it.
Please tell us your results
Good Luck

The screen when powered ON shows vertical colored lines from top to bottom. what can i do to resolve this?


Problem 1-cause from monitor or graphic card
Either the monitor is going bad or the video card is going bad. If you can get your hands on a spare monitor, try swapping it out and see if the lines are still there. If they are, then the problem is with the video card. You'll want to replace the video card if that is the case.


Solution-
Try restart your pc in safe mode. It will disable vga mode. If you are using pci-e card(external graphic card), try to change using internal graphic card to check wether that problem is cause from graphic memory problem.If your motherboard have internal memory, then you can change using internal memory. If your motherboard dont have it, that you need to buy new external memory.Before that, you can try clean and clear using eraser, to clean dirty at gold contact .
example link to follow.

Problem 2-cause from ram module
Ram modules can also cause vertical lines on a monitor.It's hard to believe but i have experienced it multiple times.The ram is detected by the system,yet the display is corrupt.If you open up the pc and touch the ram modules the lines go away.This is very rare yet a possible cause and easily overlooked.

Solution:
Same like memory graphic. Link
Try clean the dirty. Or if it cause from overheating, try using fan for ram.

Problem 3-overheating in graphic card

The video card could be over heating which causes what you are seeing, lines can also be called "Artifacts". Try opening the side of your case and see if you see these lines. Also, it could be a driver issue, try cleaning out your drivers using Driver Cleaner, and reinstalling the appropriate drivers.
If you have another computer, if the video card is a expansion video card (Meaning you have it in a PCI/AGP/PCI-E slot) try it in another computer to see if the problem persists, if so your card is probably bad and needs to be replaced.


Solution:

For this problem, actually, i try using fan.

 Absolutely is solve the problem. i'm added internal fan, modified it for to cool graphic (PCI-E). fOR THIS CASE, mostly the problem you face is your pc will restart, or suddenly your screen became white. However, you can try.


Problem 4-magnet radiation

Also check to see if there are any magnets near the screen or hard drive.

For this, make your screen like rainbow. and sometimes, it make your screen, showing the line and it also will cause problem with your pixel in screen/ monitor

I try to play a game with my graphics card installed but I keep getting a screen full of dots and after a while the computer restarts.What should I do?


Try updating your graphics driver. and lower some of the quality settings in the game so it doesn't push the card as much. If that doesn't help you may need to buy a new graphics card.

My laptop ( sony viao laptop) fell and now once turned on I have a black screen all lights and sounds are good. Could this be a led disconnect problem or a video card situation. What type of video card...


Unlikely to be a vga cable loose, but you can check by removing the switch panel cover and the screen to check it is still firmly housed.

test the laptop first in an external monitor, if you get an image, then the graphics chip is still ok

This then points to the screen, may appear undamaged, closer inspection with a torch, shone through the back of it will show any cracks you do not see straight away.

If the screen will not light up, fault is probably with a damaged backlight or inverter, you are then looking at a new (or 2nd hand) screen

Colored dotted lines across the screen


If you understand the components of a computer pretty well, open the case and remove and reseat the graphics card into the slot.

Does it seem to only do it after so long, for example turn the computer of for a few hours, and it wont happen when its first turned on, but then a few moments later it starts after its warmed up?
If this does not resolve the issue, you may be experiencing graphic artifacts which can occur when a gpu is overheating due to a poor cooler. Check to make sure the heatsink is touching the gpu.

Windows xp will not start in normal mode


This is not a good sign. If you are seeing the dots, which I am assuming they are in rows, or some line-like uniformity, when you first boot and on the Startup screen for Safe Mode (which is before Windows loads), this is an obvious indication that your video card has gone bad, and needs to be replaced. There is no software being loaded until you see the login screen to windows, or atleast the blue login screen flashes. This means you need to replace your video card. Fortunately, this is usually neither expensive, nor that hard. A decent video card can go for around $50 or more, depending on your needs. If you are a gamer or graphic designer, then a higher-end card will be more. Putting a new card in is not as hard as it may seem, but you may have experience on this. Let me know if I can be of further assistance, but this should solve your problem.

Acer screen saver keeps coming on while I'm working


It appears that you are losing the video connection between your computer and the the monitor. Remove the conector from the video card and reconnect it again, make sure the connector is firmly secure. If the problem still persists you could have a faulty video card and it needs to be replaced.

If the video card is built in on the motherboard, you still need to purchase a new video card (buy a AGP graphics card), insert into the AGP slot of your computer, you may need to disable the onboard graphics card - go into the BIOS to do this, and you need to install the new graphics card driver.
